Hey all!

Im making a donut tearing simulation with vellum grains. I use the vertexsplit node to promote the uv's from my incoming donut model, from verts to points.

I then transfer those point uv's from the original mesh to the vellum grains

And after simming and meshing the grains, i transfer the uv's from simmed grains to the meshed donut, but when i smooth the uv's, i get these weird seam lines.

Does anyone know how i can fix this?
